C# Find string between two stings !

[badguy4you]

now i have a richtextbox1 that has alot of text

what i want to achieve is search for as example "First" and "Second" in the textbox then get the strings located between them

i tried to use this but its hell slow

while((a9 = richtextbox1.Text) != null)
{
if ( line.Contains("word") )
{
string theline = line;
}

counter++;
}

versuchs mal so in etwa ...

string teststring = "ich bin First und du bist Second okay";
string newString = teststring.Substring(teststring.IndexOf("First"), teststring.IndexOf("Second"));

[badguy4you]

i dont need a specified text string i need it to search the whole richbox for these two words and get text located between them

But anywat thanks for your help and if you know how could i achieve that please tell me

What Vloxxity said was good. If you have a RichTextBox you can do it like that:

string teststring = RichTextBox1.Text; //Should be clear 
string newString = teststring.Substring(teststring.IndexOf("First"), teststring.IndexOf("Second"));
// Or a 1-line Code:
string newString = RichTextBox1.Text.Substring(RichTextBox1.Text.IndexOf("First"), RichTextBox1.Text.IndexOf("Second"));

Is that what you are searching for? The methode Vloxxity posted was enough to archieve that. And I don't think you are a C&P-Kiddie, who can't apply general methods to specific problems (then you should stop programmming immediately).

Away from the very nice sense of humor that you have... thx

string between(string str1, string str2, string str3) 
{
 int start = str1.IndexOf(str2);
 int end = str1.IndexOf(str3, start);
 return str1.Substring(start + str2.Length, end - start - str2.Length);
}

and your code does not work at all cuz the rich box i have has more that 400 line full of text so how i do that

[badguy4you]

bump

the richbox I have has more than 500 lines I want to search for the unique text "FIRST" and the other unique text "Second" and get the text between then

EX. a line container this "First time I code in C# and it is my Second time"

of meaningless sentence cuz I don't have example now but I want to get that text "time I code in C# and it is my"

NOTE: The rich box has more than 500 lines I want the fastest way to get the results desired

u can use regex to find data between 2 strings

[kissein]

u can build your own custom method

First define your SplitDefinition

public class SplitDefinition
{
    public SplitDefinition(char delimiter, string[] splits)
    {
        this.delimiter = delimiter;
        this.splits = splits;
    }

    public char delimiter { get; set; }
    public string[] splits { get; set; }
}

then use List to store your results

public List<SplitDefinition> CustomSplit(string source, char[] delimiters)
{
    List<SplitDefinition> splitDefinitionList = new List<SplitDefinition>();

    foreach(char d in delimiters)
    {
        SplitDefinition sd = new SplitDefinition(d, source.Split(d));           
        splitDefinitionList.Add(sd);
    }

    return splitDefinitionList;
}

and init it

void Main()
{
    string text = "First time I code in C# and it is my Second time";
    List<SplitDefinition> splitDefinitionList = CustomSplit(text, new char[] { 'First', 'Second' });
}

            }
